' 5 Claims.

This invention relates to a design-forming device and more particularly toa device on which designs such as petals, flowers, etc. are formed by the use of yarn, thread, etc.

An object of the invention is to provide a design-forming device of extremely simple parts which enables the design to be conveniently formed and readily released.

A further object is to provide a design-forming device constructed of very few parts and which is provided with a pedestal by which the device is supported in upright position.

A further object is to provide a design-forming device equipped with vertically movable means for releasing the design-forming prongs from the thread design. Other specific objects and advantages will appear as the specification proceeds.

The invention is illustrated in preferred embodiments, by the accompanying drawing, in which- Fig. 1 is a plan view of a device embodying my invention, yarn being shown applied to the prongs or fingers to form a petal flower design; Fig. 2, a side view in elevation; Fig. 3, a plan sectional View, the section being taken as indicated at line 3 of Fig. 2 and the yarn being removed; Fig. 4, a vertical sectional view, the section being taken as indicated at line 4 of Fig. 1, the prongs being shown in releasing position; Fig. 5, a bottom plan sectional view of a modified form of device embodying my invention, the section being taken as indicated at line 5 of Fig. 6; and Fig. 6, a vertical sectional view, the section being taken as indicated at line 6 of Fig. 5 and the prongs being shown in releasing position.

In the illustration given in Figs. 1 to 4, inclusive, l0 designates an upper forming plate and II a pedestal plate. The two plates 10 and H are connected to the ends of a fixed stem 12.

A sleeve i3 is slidably mounted on the stem l2. Fixed to the lower end of sleeve I2 is a presser plate [4. Fixed to the upper end of sleeve I3 is a prong plate IS. The prong plate I5 is preferably formed in one piece and of suitable fiexible material such as cellulose acetate, resilient metal, etc. Portions of the plate are cut away so as to provide a series of spaced fingers or prongs [6, the prongs extending a certain distance beyond the periphery of plate [0, as shown more clearly in Figs. 1 and 3. If desired, a spring II maybe placed between plates H and I4 so as to normally urge the prong plate l5 against the forming plate ill. The device may, however, be operated without a spring.

In the operation of the device, a yarn or other thread l8 may be drawn about the ends of the prongs l6 and over the forming plate Ill, as illustrated in Fig; 1 so as to form a flower or other suitable design. After the design has been formed, it is released from the device by pressing plate l4 downwardly, as'illustrated in Fig. 4, the flexible fingers l6 bending and giving the dished appearance shown in Fig. 4. When the plate It is depressed slightly further, the ends of the prongs l6 slip out of the design and the'fiower or other design may be removed. Immediately after the removal of the design, the spring I! moves the sleeve l3 and prong plate l5 back into the operative position illustrated in Figs. 1 and 2.

The device can be operated with great speed, the designs being quickly formed and released from the prongs instantaneously by downward movement of the presser plate M.

In the modification shown in Figs. 5 and 6, the construction of all of the members is substantially the same as illustrated in Figs. 1 to 4 except that the plate I5 is rigid and is provided with a series of slots having transverse pivot pins 20 extending therethrough. Mounted on the pivot pins 20 are a plurality of fingers 2|, each of the fingers having its lower end turned upon itself to provide a hinge 22 extending about pin 20.

The modified construction of Figs. 5 and 6 operates substantially the same as the device shown in Figs. 1 to 4. However, instead of having the plate l5 flex together with the prong fingers, the plate l5 remains in horizontal position while fingers 2| swing upon their pivots 20 as the plate l5 moves upwardly and downwardly. When the plate I5 is in its upper position, the prongs 2| are in extended and substantially horizontal position so as to engage the yarn, etc. After the design has been formed, the presser plate [4 is moved downwardly against the force of spring ll and the fingers 2| move to the releasing position shown in Fig. 6. A slight further downward movement of sleeve I3 causes the fingers 2| to be released from the design.

While, if desired, an outer casing may be provided for enclosing spring l1 and other changes of like character may be made, without departing from the spirit of the invention, it is believed that the present design is advantageous in that it is constructed of few parts all of which are readily accessible and because of the ease with which the sleeve can be vertically adjusted on the stem. It will be observed that the prongs, when the sleeve is moved to the upper position, are held rigidly construed as broadly as permissible, in view of the prior art.

I claim: l 1. A design-forming device, comprising: a-pair of plates, a stem fixed to said platesand support ing them in spaced relation, a sleeve movably mounted on said stem, a prong plate carried by said sleeve and being provided with yieldable 20 prongs extending beyond the periphery of said plate, and spring means urging said sleeve toward raised position.

2. A design-forming device comprising: a forming-plate, a pedestal plate, a stem connecting said 25 plates, a. sleeve slidably mounted on said stem, a prong plate carried by the upper end of said sleeve and having yieldable prongs extending beyond the periphery of said forming-plate, a presser plate secured to the lower end of said sleeve, and 0 a compression spring extending about said stem and between said pedestal plate and said presser plate, said spring urging said presser plate toward raised position.

3. In a device of the character set forth, a forming-plate, a stem secured thereto, a vertically movable plate carried by said stem, said movable plate being provided with fingers normally extending beyond said forming plate and in engagement with a thread design but moving inwardly with respect to the periphery of said forming-plate when said fingers are withdrawn f rom said thread design as said movable plate is moved downwardly.

In a device of the character set forth, a form ing plate, a stem secured thereto, a plate movably supported on said stem, and a plurality of fingers pivotally secured to said last-mentioned plate and having their end portions extending beyond the periphery of said forming plate when said last-mentioned plate is in raised position.

am a device of the character set forth, a forming plate, a pedestal plate, a stem connecting said 'plates, a sleeve movably mounted on said stem apair of plates secured tothe ends of said sleeve, the upper plate of which is equipped with yieldable prongs normally extending beyond said forming-plate, said prongs when engaged by thread extending over said forming-plate being movable inwardly with respect to the periphery of said.forming-plate to be disengaged from said thread as said sleeve is moved downwardly.
